PCB Saunier Duval Thelia 30E Ref. 05607600
The control PCB manages the ignition, burner modulation, pump, and safety features of the boiler. If it fails, the boiler may not start, lock out, or behave erratically. This PCB is compatible with the Thelia 30E model from Saunier Duval, whose manufacturer reference is 05607600. When you notice that the boiler exhibits these symptoms, it is time to replace the PCB to restore its operation.

How to check if the part number 05607600 is the correct one for your boiler.
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 05607600. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the PCB 05607600 resolves.
The PCB controls the ignition, modulation, and safety features of the boiler. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler shows no signs of life: no display, no lights, no startup noise.
Cause: If the PCB does not power its control circuits, no component of the boiler starts.
Check the main power supply, the network fuse, and ensure that the boiler transformer is supplying current to the input of the PCB.
- 02
The boiler ignites the burner but stops by itself after a few seconds, without any apparent reason.
Cause: A fault in the control stage of the PCB can cut off the ignition signal even if the rest is functioning well.
Check that the sensors and pressure switches connected to the PCB are giving the correct readings before assuming that the PCB is the culprit.
- 03
The pump or the fan stays on even when the boiler is in standby.
Cause: One of the relays on the PCB that controls these components gets stuck in the closed position.
Listen for the relay clicking when switching from standby to demand; if it doesn't change state, the relay on the PCB may be the issue.
- 04
The thermostat is calling for heat, but the boiler is not responding, as if it doesn't hear it.
Cause: The stage of the PCB that receives the signal from the thermostat is not processing the command.
Check that the thermostat closes the contact correctly and that the wiring to the PCB is not cut.
- 05
The boiler is acting erratically: sometimes it ignites properly and other times it locks out without any pattern.
Cause: The tracks or solder joints on the PCB degrade with heat and humidity, causing intermittent faults.
Open the casing and check for any signs of rust, moisture, or components with marks of having overheated before declaring the PCB faulty.
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
